摘要
Abstract
The Lop Nur playa is located in the eastern Tarim Basin, Xinjiang. Since 1995, a superlarge brine potash deposit had been found in the Lop Nur and the brines are mainly stoerd in salt strata in the Luobei sag. In recent years, researchers have found that graben fault depression zones are developed in Lop Nur, which not only controlled the formation of the potassium depression, but also contained a certain amount of solid potash resources. Geophysical measurements (EH - 4) showed that the rift zone can be as deep as 1000 m. During the evolution of the Lop Nur salt lake, there were smaller depressions or salt lakes existed in the faulted belt. The surface water evaporated and concentrated into brines. As the graben faulted belt can be up to 30 ~ 50 km at length, extending to 1000m at depth, the faulted zones can form and reserve a certain scale of solid potash ore, which should become the new prospecting area in Lop Nur for more potash resources in the future.关键词
